      Description

      HDFS Federation documentation
      http://hadoop.apache.org/docs/r2.6.0/hadoop-project-dist/hadoop-hdfs/Federation.html
      has the following command to add a namenode to existing cluster

      > $HADOOP_PREFIX_HOME/bin/hdfs dfadmin -refreshNameNode <datanode_host_name>:<datanode_rpc_port>

      this command is incorrect, actual correct command is

      > $HADOOP_PREFIX_HOME/bin/hdfs dfsadmin -refreshNamenodes <datanode_host_name>:<datanode_rpc_port>

      need to update the same in documentation
